Electromagnetic wave
Understand the Problem
The question is asking for information regarding electromagnetic waves, which are waves of energy that travel through space and are composed of oscillating electric and magnetic fields. The query likely seeks a definition or explanation of their properties, behaviors, and applications.
Answer
Waves of electric and magnetic fields propagating through space.
Electromagnetic waves are waves of electric and magnetic fields that propagate through space, carrying energy and momentum at the speed of light.
Answer for screen readers
Electromagnetic waves are waves of electric and magnetic fields that propagate through space, carrying energy and momentum at the speed of light.
More Information
Electromagnetic waves include a wide range of different types, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, all of which differ in frequency and wavelength.
Tips
Confusing electromagnetic waves with mechanical waves that require a medium to travel through can be a common mistake. Remember that electromagnetic waves do not require a medium.
